Six Degrees of Paul Erdos Contrary to popular belief‎,‎ mathematicians do quite often have fun‎.‎ Take‎,‎ for example‎,‎ the phenomenon of the Erdos number‎.‎ Paul Erdos ‎(‎1913‎-1996‎)‎‎,‎ a prominent and productive Hungarian mathematician who traveled the world collaborating with other mathematicians on his research papers‎.‎ Ultimately‎,‎ Erdos published about 1‎,‎400 papers‎,‎ by far the most published by any individual mathematician‎.‎ About 1970‎,‎ a group of Erdos‎'‎s friends and collaborators created the concept of the ‎"‎Erdos number‎"‎ to define the ‎"‎collaborative distance‎"‎ between Erdos and other mathematicians‎.‎ Erdos himself was assigned an Erdos number of 0‎.‎ A mathematician who collaborated directly with Erdos himself on a paper ‎(‎there are 511 such individuals‎)‎ has an Erdos number of 1‎.‎ A mathematician who collaborated with one of those 511 mathematicians would have an Erdos number of 2‎,‎ and so on ‎-‎- there are several thousand mathematicians with a 2‎.‎ From this humble beginning‎,‎ the mathematical elaboration of the Erdos number quickly became more and more elaborate‎,‎ involving mean Erdos numbers‎,‎ finite Erdos numbers‎,‎ and others‎.‎ In all‎,‎ it is believed that about 200‎,‎000 mathematicians have an assigned Erdos number now‎,‎ and 90 percent of the world‎'‎s active mathematicians have an Erdos number lower than 8‎.‎ It‎'‎s somewhat similar to the well‎-known Hollywood trivia game‎,‎ Six Degrees of Kevin Bacon‎.‎ In fact there are some crossovers‎:‎ Actress‎-mathematician Danica McKellar‎,‎ who appeared in TV‎'‎s The Wonder Years‎,‎ has an Erdos number of 4 and a Bacon number of 2‎.‎ This is all leading up to the fact that Gary Chartrand‎,‎ author of Dover‎'‎s Introductory Graph Theory‎,‎ has an Erdos number of 1 ‎-‎- and is one of many Dover authors who share this honor‎.‎
